This application relates to the field of cold cathode field emission material preparation technology, and discloses a method for preparing a graphene-diamond composite structure to improve the field emission performance of diamond. The method involves first dispersing nanodiamonds and graphene oxide in a deep eutectic solvent; then adding boric acid to induce an in-situ sol-gel transformation under heating, forming a gel network that locks the dispersed phase; followed by microwave-assisted interface activation and gradient high-temperature carbonization, and finally cleaning and drying to obtain the product. This invention effectively suppresses phase separation and agglomeration during pyrolysis through a gel solidification mechanism, and utilizes the deep eutectic solvent and boric acid pyrolysis to achieve in-situ co-doping of nitrogen and boron, constructing a low-barrier continuous conductive channel on the diamond surface, and realizing tight electrical interconnection between components. This method is simple and controllable, and the resulting composite material possesses excellent conductivity, low turn-on electric field, and high emission stability, thus improving the electron emission efficiency of cold cathode devices.

This invention discloses a belt anti-scratch system and method for a belt sampling machine. The system includes a support frame, a protective cover, and a main controller. The support frame is mounted on the belt conveyor frame, with the protective cover connected to its upper part. Industrial cameras are installed inside the protective cover and at the bottom of the belt for real-time monitoring of the belt's condition. A rotating support is mounted on the support frame, with a rotating shaft passing through the protective cover. One end of the shaft is connected to a reducer and a motor, while the other end holds a sampling head placed inside the protective cover, forming a rotatable sampling structure. The main controller is electrically connected to the industrial cameras and the motor. It acquires belt image data through the industrial cameras, processes the data, and then controls the motor to drive the sampling head, achieving monitoring of the belt's operating status and anti-scratch control during the sampling process. Through structural integration and intelligent control, this system effectively prevents the sampling head from scratching the belt, improving the safety and reliability of equipment operation.
